Abstract | In this paper we investigate the performance of array codes and in particular generalised array codes (GAC) and row and column array codes (RAC) as coding schemes in the power line communications (PLC) environment. We apply different code rates and modulation techniques and we examine how these codes perform in the hostile channel of power lines in terms of BER (bit error rate) versus $E_{b}$ / $N_{0}$ (signal to noise power). In addition, we propose a variation concerning the construction of GAC codes. As a result we get a code which has the same code rate with the original GAC code; however it is derived from an altered construction. QPSK and 8PSK modulation schemes are being used for the system's realisation. Furthermore, we compare the codes' performance with convolutional codes. For the power line channel, we exploit Zimmermann's model, while Middleton's class A noise model is used to represent the channel's noise. For reasons of completeness, we examine the effect of the noise model's parameters on the channel's performance, by using different values for them. Finally, the transmission technique of OFDM is also taken under consideration, meaning that data is transmitted in terms of blocks simultaneously. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
